Key takeaway: Cashing out from prediction markets generally requires converting your holdings to USDC (or USD), moving funds to your own wallet or financial institution, and then exchanging for your home currency. Depending on your chosen platform and withdrawal method, this can take anywhere from a few minutes up to three business days.
Understanding how to withdraw from prediction markets matters as much as mastering deposits and trades. Most beginners concentrate on acquiring shares but encounter unexpected complexity when it comes time to realise their gains. This comprehensive guide addresses all leading platforms.
Withdrawing from Polymarket
- Exit your position — liquidate your shares via the order book (alternatively, hold until market settlement for the complete settlement amount)
- Go to Portfolio → Withdraw
- Pick your withdrawal chain — Polygon (minimal cost, nearly instant) or Ethereum (steeper gas costs, 5-15 minutes)
- Supply your wallet address — verify multiple times; once sent on the blockchain, transactions cannot be reversed
- Authorise the transaction — your USDC should land in your external wallet between 1-10 minutes when using Polygon
- Exchange to fiat currency — transfer USDC to Coinbase, Kraken, or Binance and trade for EUR/USD/GBP, then move to your bank account

Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal stuck in processing for extended periods | Blockchain delays or regulatory screening | Allow 24 hours to pass, then reach out to customer service |
| Incorrect chain used | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| Identity verification required again | Substantial withdrawal activates additional compliance procedures | Furnish the necessary paperwork without delay |
| Minimum withdrawal threshold | Platform enforces a floor amount for withdrawals | Add funds to your account to reach the required level |
Withdrawal Fees by Platform
| Platform | Method | Fee | Speed |
| Polymarket | Polygon USDC | < $0.01 | 1-5 min |
| Kalshi | ACH | Free | 1-3 days |
| Kalshi | Wire | $25 | Same day |
| PolyGram | Polygon USDC | Free | 1-10 min |
Tax Implications of Withdrawals
The act of withdrawing funds itself does not create a taxable moment — however, selling your shares (exiting your position) absolutely does. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
